Answer:

A cooling curve of a substance is a graph of the variation of the temperature with time as it is allowed to cool. The gradient of the cooling curve is related to the heat capacity, the thermal conductivity of the substance, and the external temperature.

The cooling curve is one of the most accurate and widely used methods to measure the freezing point of foods. The wide application of this method is due to its accuracy and simplicity. In cooling curve method the sample time–temperature is recorded by a temperature-indicating device.

Answer:

36π

Step-by-step explanation:

Since we are given the equation and the value for m, we can plug it into the equation to solve for the area:

Area = πm²

Area = π6²

Area = 36π

Answer:la pregunta es qué tanto por ciento de 25 es 22

entonces En este caso ese todo es 25

luego por regla de tres si 25 es el 100%

22= 2200/25 =88%

Respuesta 22 es el 88% de 25

para comprobar= 88x25 /100=22 y es correcto

Answer:

tan(θ)=(√15/7)

The sign of tangent value in 3rd quadrant will be positive.

cos(θ)=-7/8

(sin(θ))^2

=1-(cos(θ))^2

=1-(7/8)^2

=1-(49/64)

=(64-49)/64

=15/64

sin(θ)=[tex]-\sqrt{15/64}[/tex]

[tex]=-\sqrt{15}/8[/tex]

[since in quadrant III value of sin(θ) will be negative]

so, tan(θ)=sin(θ)/cos(θ)=[tex]\frac{\frac{-\sqrt{15}}{8} }{-\frac{7}{8} }[/tex]=[tex]\frac{\sqrt{15} }{7}[/tex]

tan(θ)=(√15/7)

Answer:

y=2/3x-6

Step-by-step explanation:

rise over run

starts at -6

The required equation of the line is y = 2x/3 - 6

The equation of line is an algebraic form of representing the set of points, which together form a line in a coordinate system.

Given that The graph of a linear equation passes through (0, -6) and (9,0).

We know that the equation of line passing through two point is;

y-y₁ = y₂-y₁ / x₂-x₁ (x-x₁)

Therefore, y+6 = 6/9(x-0)

y = 2x/3 - 6

Hence, the required equation of the line is y = 2x/3 - 6

Answer:

The third prime factor is 5.

Step-by-step explanation:

What you have so far is 18

You need to multiply 18 by something to get 90

The easiest way about finding out what the fact is is to set up this equation

18*x = 90                 Divide by 18

x = 90/18

x  = 5                        5 is a prime factor, you don't need to break it down.

Logan need to drive at 32 mile per hour to get to work exactly on time

Speed is the ratio of the total distance travelled to the total time taken. It is given by:

Speed = distance / time

Let d represent the distance from t represent the time in which he is early. Hence when he is 5 minutes (0.083 hour) late:

When 5 minutes early:

Solving equations 1 and 2 simultaneously gives:

d = 8, t = 0.25

speed = 8/0.25 = 32 mile per hour
